Abstract:Inaccurate speed control of unattended roller in complex rolling environment will cause rolling road damage. According to the reactive navigation control strategy and based on the PID control algorithm,the artificial directional learning direction control method is studied,and the online adaptive tuning of PID parameters is carried out through the repetitive learning algorithm. The path tracking speed control strategy was developed according to the operator’s preview model,and the optimal learning path tracking speed control strategy was adopted to achieve the smooth control of the unmanned roller.
Keywords:unmanned control roller;PID control;optimal learning algorithm;artificial control
